Specification forming part of Letters Patent No.

215,661, dated May 20, 1879; application filed March 8, 1879.

To all whom it may concern:

Be it known that I, MERRITT W. PALMER, of Schoolcraft, in the county ofKalamazoo and State of Michigan, have invented a new and valuableImprovement in Windmills; and I do hereby declare that the following isa full, clear, and exact description of the construction and operationof the same, reference being had to the annexed drawings, making a partof this specification, and to the letters and figures of referencemarked thereon.

Figure 1 is a side elevation of a windmill embodying the improvements inmy invention, and Fig. 2 is a plan view of the same.

My invention relates to windmills; and it consists in the constructionand arrangement of vanes used in connection with the windwheel, as willbe hereinafter more fully set forth.

The annexed drawings, to which reference is made, fully illustrate myinvention.

A represents the tower of the windmi1l,constructed in any suitablemanner, and B is the turn-table, provided with a hollow or tubularjournal, 0, which is inserted in the upper end of the tower. Theturn-table B is constructed to form a hearing at a for the shaft of thewheel D, said shaft having at its inner end a crank, b, which, by apitman, e, is connected with a lever, 67. This lever is pivoted to anarm projecting from the turn-table, and its inner free end is to beconnected with the rod of the pump or other machinery to give the same areciprocatin g motion.

In suitable hearings on the turn-table is placed a shaft, f, to whichthe tail-vane F is secured, said shaft f being on a line with, orparallel to, the wheel-shaft; and on the inner end of the said shaft fis a crank, i, for attaching a cord or wire, h, for the purpose ofthrowing the wheel out of the wind when desired.

To the shaft f is secured an arm, k, on one end of which is anadjustable weight, G, for holding the vane F in position to keep thewheel in the wind. The other end of the arm is is, by a coupling, a,connected with an arm, m, projecting from a shaft, p, and this shaft isplaced in suitable bearings at right angles to the shaftf. On one end ofthe shaft 19 is secured a vane, H, the planeof whichis at right anglesto that of the vane F; or, in other words, when one vane standsvertically the other is horizontal, and vice versa. Upon the other endof the shaft 17 is attached a vane, I, which 'stands in inclinedposition, as shown. This Kane 1 turns backward when the wind blows toohard, and turns the shaft 1) in its bearings; and this shaft beingconnected, as described, with the shaft f, the two vanes F and H areturned in such a manner as to throw the wheel more or less out of thewind. As the wind decreases in force the weight G brings the vanes backto their former position, and causes thereby the wheel to be thrown intothe wind.

To an arm, J, projecting from the turn-table, is pivoted a lever, K,carrying at the outer end a vane, L. The inner end of this lever K is,by a rod, 1', connected with an arm, 8, project ing from the shaft 1).

The vanes L and I are not intended to be used at the same time, thoughthey may be so used, if desired.

The action of the vane L is the same as that described for the "ane I-;but it has greater power, on account of the leverage exerted by thelever J and the connection of the same with the shaft 1).

I claim- The shaft 1), carrying the vanes H and I, in combination withthe shaft f, vane F, and arm k, with weight G, as and for the purposesherein set forth.

In testimony that I claim the above I have hereunto subscribed my namein the presence of two witnesses.
